Cool cars!
This might just be my personal preference, but I would have stepped back a little or zoomed out to include more of the background. The cars seem to take up too much of the space in the photos.

I am by no means a professional photographer, so don't take my comments to seriously!

Wow! Those look really good to me, I like them. Only thing I could think of is maybe just very slightly zoom out to show just a tad more background. Other than that, fantastic! Editing is pretty good too.

I like the E55 shot very much; if any nitpick it would be for a smaller aperture / longer exposure to have a larger area of focus (so the front of the car as it goes away from the lens plane would be sharper).

Wow, you certainly get some exotic machines to shoot !
I love this one and your Canon 50D with 70 - 200 f/4L at 200mm has nicely captured it and given a nice perspective. Your 1/1000sec shutter speed has also nicely 'frozen' the car, which is pin sharp.

Now, I hope you don't mind, but I took the liberty of having a look at your image, as I think the car, being such a dynamic colour, demands a little stronger processing. More colour and contrast mainly.

Here's an effort to show you what I mean.
If you'd rather I didn't alter your images, please say.

Alan - I appreciate the feedback. As you can tell, like many on this forum, I'm an amateur at best when it comes to photography. I'm also an amateur when it comes to Lightroom, and enjoy playing with all the different sliders and settings. I don't have a set "style", so at times go with a vibrant look, or in this case, a more washed out look. I like the way you edited it as well, as of course the yellow is very striking.
